Indigenous populations studied typically consume diets where linoleic acid constitutes about 2% of fat intake, contrasting with 7-15% in Western diets.

“you want to be around three percent linoleic acid in your diet a whole lot more than that isn't very evolutionarily consistent”

“most of the indigenous cultures are down here you guys yeah down here and and you can see this just it's incredible we this is one of the reasons that and i've talked about this with ivor cummins on this podcast in the past this is one of the reasons that epidemiology can be so confusing if everyone in the in the population has massive amounts of linoleic acid even the people eating the least linoleic acid are probably eating too much linoleic acid so you're not going to see a signal that linoleic acid is necessarily causing disease when you do an epidemiology observational study in the u.s population in 2010 or 2020 because everybody is eating five to ten times more than they should be so even the lowest group is probably at a toxic level and that's very scary that's the problem with epidemiology”

“if you're studying populations of humans and you're looking at high versus low levels of linoleic acid the low group had better have a very low level of linoleic acid as an ancestrally low level of linoleic acid which is around the level of less than two percent or fewer calories from linoleic acid in your diet”

“it's very hard to find in wild quote diets”

“there does appear to be an evolutionary inconsistency over the last 100 to 150 years in the amount of linoleic acid that we are consuming”

“it's this seems to have to happen for everything else to happen afterwards and it all kind of comes back to an evolutionarily inconsistent consumption over consumption of this fatty acid that's pretty rare in nature generally found in seeds but not found a lot of other places that in the last 150 years we've been consuming in massive quantities”

“Chris Kenobi when he's looked at indigenous populations can I hear him throw around that number two percent a lot versus seven to ten or eleven or fifteen percent”

“they get about 2% of their calories from this fatty acid that I think is evolutionarily consistent”

“there's a recent study that i was going to share with you stefan goyene did a study and you can look now traditionally i think that the set point for humans is around two percent linoleic acid for calories we're up to 10 15. some people 17 of our calories are coming from linoleic acid and that's been documented in the human diet over the last maybe even 50 to 60 years we've gone massively up in the linoleic acid”

“you can look at hunter-gatherer tribes and this has been done i talked to a gentleman on my podcast about this and you know you can look at these tribes and they consistently have maybe two percent of their calories from linoleic acid there's a recent study that i was going to share with you stefan goyene did a study and you can look now traditionally i think that the set point for humans is around two percent linoleic”

“they also weren't eating tons of linoleic acid because they were not eating a lot of seeds seeds are very hard to get they're seasonal they probably make you fat anyway”

“If you look at hunter-gatherer cultures like the Hadza, the !Kung, or humans living in the wild, their consumption is 2% of their calories from linoleic acid. Our consumption of linoleic acid is often 15 plus percent of our calories.”

“The Hadza, other hunter-gatherer groups, only eat about 2% of their calories from linoleic acid. There's probably a biological threshold for this.”

“evolutionarily our consumption of linoleic acid in 2022 seems fairly inconsistent with what we would have done as humans for the last 350 000 years yeah on average is probably five to ten times higher I think uh when they booked up again the closest we can get to is is modern um Hunter Gallery populations and it's probably two to three percent of of calories”

“evolutionarily our consumption of linoleic acid in 2022 seems fairly inconsistent with what we would have done as humans for the last 350 000 years yeah on average is probably five to ten times higher”

“and they're they're quite interesting and you look at them you look at catavans you look at the hadza indigenous groups eating their native diet really only get two to three percent of their calories from linoleic acid”

“so that's a very interesting distinction for people to understand and the whole framework of this is that when we have excess amounts of polyunsaturated fats they accumulate in the human body and we'll talk about this also in the podcast it takes us probably two plus years to get rid of them based on our physiology right so if we look at um omega-6 linoleic acid in the American diet through history this is I think is a critically important because”

“what are we back to you must eat an evolutionarily consistent amounts of linolic acid in your diet which means completely eliminating seed oils but also being very careful with things like mainstream chicken pork bacon fat Etc”

“things that we would never have really been doing historically as humans 200,000 years ago, even up until 50 or 20,000 years ago, we didn't have much of these oils in our diets.”

“Rewind the clock 10,000 years. It would have been nearly impossible to get more than 2% linoleic acid in your diet. Today, the average American eats 7 to 12% of their calories from linoleic acid per day.”
